Convert JPG to ICO
What is JPG?
JPG
JPG uses lossy DCT compression with 8×8 pixel blocks, ideal for photographs with smooth color gradients. Compression ratios range from 10:1 to 20:1 depending on quality settings. Maximum resolution 65,535×65,535 pixels. No transparency support (unlike PNG). Supports EXIF metadata for camera information. Best for photographs; poor for graphics with sharp edges, text, or solid colors due to compression artifacts.
- JPG uses lossy compression for efficient image storage
- Lossy compression means conversion to ICO preserves but cannot restore quality
- DCT-based compression removes high-frequency visual data
- Supports 24-bit RGB color (16.7 million colors)
- Universal browser and device support—no compatibility concerns
What is ICO?
ICO

Supports transparency.
- ICO uses lossless compression for perfect quality image storage
